Hi Everyone,
We have released a worksheet to assist you in developing initial cost estimates for the Rio Tinto Ore Upgrading Challenge. A completed cost estimate worksheet is a required deliverable for your Challenge submission.
You may access the Cost Worksheet in the Resources section of the Challenge Page: https://www.herox.com/OreUpgrading/resources
We recognize that at an 'idea-stage' of development, that accurate cost estimates will not be possible. At the same time, our overall objective is to identify cost-effective new technologies that can improve our TiO2 content, so cost feasibility of the approach is central to the Challenge.
Our initial focus for evaluating costs will be related to operating costs (Opex). Capital expenditures (Capex) required for any proposed concept will be evaluated at a later stage of development (during our Stage-2 Challenge).
The worksheet includes cost estimates for all production consumables, labor, maintenance and power (process-related) for your conceptual solution. Guidance is also provided for completing the worksheet below and to the right of each section. Note that green cells denote where direct input is allowed; grey cells are protected (locked) to prevent accidental overwriting of formulas.
If you have any questions, please post them in the Challenge Forum.
